Плохо, но скорее всего сработает. ffmpeg -f x11grab -r 5 -s $(xwininfo -root | grep 'geometry' | awk '{print $2;}') -i :0.0 -an -vcodec flv -vb 1000 -y $(date "+%F-%H-%M-%S").flv

ffmpeg -f x11grab -r 4 -s $(xwininfo -root | grep 'geometry' | awk '{print $2;}') -i :0.0 -an -vcodec flashsv -vb 1000 -vsync 1 -y $(date "+%F-%H-%M-%S").flv
